Two recent contracts in China illustrate how waterworks and utilities are using butterfly valves to reduce energy use.
NF Energy Saving Corp. is supplying 24 sets of butterfly valves to a major water supply project in Guangzhou, China, according to a press release.
These particular butterfly valves are massive, with a diameter in excess of 10 feet, and have a working life of 30 years. In total, the deal is worth more than $2.2 million.
The advanced sealing and flexible open technology properties of the valves make them more energy efficient, according to a press release.
NF's Chairman and CEO, Li Gang, said that the energy efficient flow control system will help secure water supplies for the upcoming Asian Games in Guangzhou.
Butterfly valves require less depth of cover during installation, and thus less concrete required to cover the valve chamber, with an accompanying reduction of CO2 emissions, according to PlumbingPark.
In another example, NF is supplying six sets of butterfly valves to a coal plant under construction in Zhejian province, reports Proactive Investors. That deal is worth $550,000.
The new coal plant is one of a breed of so-called ultra-supercritical power plants designed to replace smaller, inefficient and pollution-belching plants.
